From 88af29f3aba662aab4ca5ac3122d43139fb97004 Mon Sep 17 00:00:00 2001 From: Micah Anderson Date: Tue, 17 Dec 2013 15:43:58 -0500 Subject: Fix for openvpn/unbound not starting at boot (#4506) This change sets the sysctl net.ipv4.ip_nonlocal_bind to allow applications to bind to an address, even when the link is down. This is necessary because applications like unbound and openvpn fail to start on boot in some situations because interfaces are not fully up (due to a combination of non-deterministic booting because of the likely potential setting of allow-hotplug in the interfaces file and the LSB boot dependency on $network not being sufficient. The only down-side to setting this is a daemon could bind to an incorrect ip and we wouldn't get an error, but this would be a configuration mistake, rather than a fatal condition.
